I am trying to add calendar from this URL http://windows.microsoft.com/en-us/windows/outlook/calendar-holiday-other

I've read a lot of the posts from here but couldn't find an answer for the this issue. It for every single calendar that I am trying to subscribe, I am getting this error "There's a problem with the calendar URL that you entered. Please make sure you've entered it correctly and try again."

Even I tried to open this web calendar from Outlook 2013 client using the URL "webcals://calendar.calendar.live.com/calendar/Malaysia Holidays/calendar.ics" it also doesn't show me anything.

Previously I still got Singapore Holiday calendar that is working fine. But after I deleted it now I cant subscribe it back also.

Is it anything wrong with my account or not? Because recently I just switched my Microsoft account from Hotmail to Outlook as Primary.
